Title: Improvements in or relating to television receivers
Inventor: GERMANY LESLIE WALTER
IPC: H04N5/53
Filed: 1950-05-17
Abstract: 685,862. Automatic gain control. PYE, Ltd. May 17, 1951 [May 17, 1950], No. 12372/50. Class 40 (v). In a television receiver in which an A.C.C. voltage is derived from the black level by gating the video waveform during the black level periods, the pulses so formed are fed through a noise limiter circuit before smoothing. Positive video signals, i.e. poled, so that the synchronizing signals are negative-going, are applied to the grid of a " gate " valve V1 which is rendered conductive only during the " back porch " period succeeding each of the synch. pulses. " Gating " is performed by positivegoing impulses applied to the suppressor grid and which comprise delayed and reversed synchronizing pulses obtained from the signal by means of a phase-reversing valve V7 and delay line L; a diode V3 provides D.C. restoration. Negative-going impulses of amplitude proportional to that of the black level appear at the anode of the valve V1 and are applied over a series-type noise limiter comprising a diode V2 and time-constant circuit R, C, to an amplifier V4. The peaks of the positive-going pulses produced in the anode circuit of the valve V4 are maintained at a potential corresponding to the setting of a potentiometer P by means of a D.C. restoring diode V5; the potential at the anode of this valve is smoothed by an R.C. network and constitutes the A.G.C. potential. A diode V6 prevents the application of positive potentials to the grids of the controlled valves.

Title: Improvements relating to automatic switches of the kind used in telephone systems
IPC: H01H67/06
Filed: 1947-07-09
Abstract: 638,916. Electric motors. SIEMENS BROS. & CO., Ltd., and CHRISTIAN, D. A. July 9, 1947, No. 12669. [Class 35] [Also in Groups XXXIV and XXXIX] In an automatic selector switch of the type individually driven by an electromotor, the rotor is brought to rest at the end of the setting movement by a magnetic braking device which acts at a time when the stator of the electromotor is exerting little or no driving torque on the rotor. In Fig. 1, a rotor R, a cam K, a braking switch wiper W and the armature of the braking device AR are securely attached to a shaft DS which also drives a wiper shaft through gearing G. With the rotor R in the position shown, winding I of driving electromagnet N, relay NR and relay CM are energized when relay A (not shown) responds to each incoming impulse, the relay CM ensuring that the circuit to winding 1 of the driving electromagnet M is held open when the cam K moves away. The electromagnet N and relay NR are locked up over winding II of N. Rotation of the shaft DS through 90 degrees due to the energization of N mechanically operates contacts CNS, thus energizing the relay CN and brings the wiper W to the next contact segment WS, thus energizing the coil BW via contact ring WF and attracting the ends of the flexible armature AR to the pole BF to provide friction braking. An air gap BG ensures quick release. In the embodiment, Fig. 4 (not shown), a permanent magnet PM which attracts the armature for braking purposes is neutralized during rotation by a coil energized over intermediate contact segments of the braking switch. In a third embodiment, Fig. 5 (not shown), four portions of the pole face BF are cut away so as to leave four isolated braking pole faces corresponding to the positions in which stopping is required and the braking is effected alternately by one of two coils wound to give opposite directions of magnetization. The reversals are retarded by a copper collar which enables the brake armature to move clear of its last braking polepiece before the reversed magnetization becomes effective.

Title: Improvements in or relating to printing telegraph apparatus
IPC: H04L17/20
Filed: 1937-05-04
Abstract: 483,355. Type - printing telegraphy. CREED & CO., Ltd. May 4, 1937, No. 12710. Convention date, July 15, 1936. [Class 40 (iii)] Apparatus for printing a tape with code indications, for use particularly with a photoelectric transmitter, comprises a rotary member carrying code-printing elements, and a further rotary member which places a printing hammer under the control of a signal-receiving magnet at intervals corresponding to the signalling periods. In the apparatus shown, a motor-driven worm-wheel 14 drives through friction clutches a shaft 15, a notched disc 28, and a sleeve carrying staggered type elements 29. At each signal period, a pawl 42 connected to the printing hammer 39 is opposite a notch in the disc 28 and if the signal-receiving magnet 53 is energized to indicate a marking signal its armature 49 withdraws an arm 47 from a lug 46 so that the printing hammer rises to press the tape against the corresponding type element. The shaft 15 is stopped in its normal position by an arm 58 engaging a member 62. On the receipt of a start (spacing) signal, an arm 79 on armature 49 acts through a bell-crank 77 on a lever 68 causing the disengagement of the latter from member 62 which then rocks on its pivot to free the shaft. To adjust the stopping position angularly, members 62, 68 are mounted on an arcuate plate 85 pivoted on frame 87 and locked in adjusted position by a nut- 89. During the receipt of signal impulses, the armature 49 is freed from the influence of crank 77 by a member 94 controlled by a cam 22. A further cam 23 provided with teeth controls arms 79 so that the armature is moved close to the magnet at each signal period to minimize the current required for attraction. The tape is fed continuously over a table 142, provided with adjustable tensioning springs 143, by a sprocket wheel 108 driven through gearing from worm 26, the direction of the tape being turned through a right-angle before reaching table 142 by a pivoted self-adjusting roller. Owing to the continuous drive of the tape, the lines of printed elements are inclined across the tape as shown in Fig. 12, but perpendicular lines may be obtained by progressively displacing the notches in disc 28 relatively to the type elements 29. A narrower tape, Fig. 13, with two rows of markings for each letter, may be employed by suitably arranging the type elements as shown.

Heading F2F. A tractor-trailer braking system comprises independent hydraulic circuits for operating hydraulic wheel cylinders of tractor and trailer respectively, the tractor circuit including a master cylinder acting directly on the tractor wheel cylinder, and a vacuum servo including a slave cylinder acting on the hydraulic circuit of the trailer, the vacuum servo being controlled by a relay valve acted on by pressure derived from the master cylinder via a pressurereducing valve. In one embodiment, Fig. 1, master cylinder 1 acts directly on wheel cylinders 7 of the tractor and via a pressurereducing valve 2 on relay valve 10 of vacuum servo 3 the vacuum for which is obtained from the inlet manifold 11 via check valve 12 and reservoir 5. Hydraulic slave cylinder 8 has its own reservoir 4 and is independent of the circuit including master cylinder 1. A pipe 9 connects slave cylinder 8 to a coupling 6, 14, incorporating a pressure multiplier, the part 14 of which is on the trailer and connected to the trailer hydraulic circuit. In the modification of Fig. 2, the vacuum servo 3, the reservoirs 4, 5 and the check valve 12 are disposed on the trailer and a coupling 13 is provided to connect the valve 12 to the inlet manifold on the tractor in addition to a coupling 14 for connecting the relay valve 10 to the pressure reducer 2 (not shown) associated with the master cylinder on the tractor. The system is otherwise identical and operates as in the Fig. 1 embodiment, excepting that a hand lever 16 provided on the coupling 14 is adapted to act on a secondary master cylinder so that pressure can be introduced manually into pipe 15 to operate relay valve 10 for applying the trailer brakes when disconnected from the tractor, the reservoir 5 storing a vacuum for operating the vacuum servo. The vacuum servo itself, Fig. 3, is of the vacuum-suspended type and comprises a power piston 23 separating vacuum chambers 24, 25, air being admitted to the chamber 24 by an inlet valve 35 when increasing hydraulic pressure acts on a control piston 22. A perforated diaphragm 37 is moved by the latter against a valve 36 to cut off chamber 24 from the vacuum in chamber 25, whereby increasing pressure in chamber 24 acts on the. diaphragm to close the inlet valve when the pressure in chamber 24 corresponds to the hydraulic control pressure.
